Dispersive CFT Sum Rules

Dispersion relations have emerged in recent years as a powerful analytic tool to study CFT correlators. Similar to their scattering amplitude counterparts, these dispersion relations leverage the analytic structure and "absorptive properties" of correlators to reveal consistency sum rules on the spectrum of CFTs. In this talk, I will review the literature on recent applications of dispersion relations in the context of CFTs, and I will present recent work generalizing the use of dispersive CFT sum rules to mixed correlators.
